町民見学会の様子

【2025年1月16日開催レポート】 
 ニセコ町子ども議会議員のみなさんと、新幹線のトンネル見学に行ってきました!現在、ニセコ町内では、 札幌まで延伸を予定している北海道新幹線のトンネル掘削工事が行われています。今回は、北海道新幹線への理解を深めることや将来の新幹線利用に向けたきっかけとなるよう、子ども議会議員のみなさんに向けたトンネル見学会を実施しました。見学会では、鉄道運輸機構の方が新幹線やトンネルに関する説明を、パワーポイントや実際の現場を見学しながら説明していました。子どもたちは、事前に子どもまちづくり委員の活動で、ニセコ町のまちづくりに関して学んでいたこともあり、興味津々な様子でした。
